I know that you do what it takes to get the aeroplane down in a field - but after a very few hours do you even have the basic 'stick and rudder' skills to do that?
You have to go sometime, I agree. I'm not suggesting that you should be able to fly a navex before you solo. However, a few extra hours covering the what-ifs gives a bit more experience in flying the aeroplane, which is helpful in itself, but many times the experience of flying the aeroplane in an 'emergency' - if you solo in a handful of hours how many PFLs or EFATOs can you have done? What about stall/spin avoidance? What about dealing with the dumb things we all do from time to time, like the infamous mixture-heat check downwind (been there, done that). I'm just finding it hard to see how someone learning ab initio can cover this stuff well and still solo in 6 hours. There just isn't time.
